Re: [ubuntu-uk] Borked my Mac installing Ubuntu 11.04, now blackscreens beeps on restart then takes exactly 4 attempts to boot
Hi -- a few other people have seen this, so I thought I'd post the links here, for anyone interested. * https://bugs.launchpad.net/ubuntu/+bug/774089 * http://pubmem.wordpress.com/2011/04/09/flash-efi-firmware-update-manually-on-a-macbook-51/ The second article looks like the answer. Unfortunately, there are firmware updates available for all *but* my model (MBP 5,4), so it looks like I'm going to have to talk to someone at Apple to find out what firmware package I can use.

Anyway, in the hope that some local talent may see this know what's going wrong ... Hi -- I've tried to install 11.04 on my Macbook Pro (5,4) today. I had two drives in the machine, an SSD as my main drive, and an HD. I installed rEFIt before attempting to install Ubuntu. I moved my Snow Leopard install to the secondary HD made sure I could boot to it. Then, I used the live CD gparted to clear the 1st drive (the SSD), create the swap space, create the Ubuntu partition, and launch the install, where I used what I had just created on the SSD. The install completed okay (but with no option to select where the GRUB installer went, like some tutorials tell you to look out for). This seemed to go okay, so I went to restart at the end of the install, but the machine didn't come back up. Instead, the power came on I could hear the drives, but the screen stayed black, the battery light flashed a load of times really quickly (too quickly to count, but at least 10 times), and then the machine let out 1 long beep and stayed on the black screen. I forced it to power down tried again, and just got a black screen, the battery light shining steadily, and no beep. I forced it to power down again, and got the same, then again, and got the same, and then a 4th time, which actually allowed me to boot. And this has been the pattern since then. I shut down, and my first attempt to restart gets me the flashing light and the beep, with the black screen. I try 3 more times to power down and restart, and just get the black screen. Then, *every* time on the 4th time, I'm allowed to boot. The same routine will be gone through the next time I power down and try to restart. I've tried totally clearing the disk in gparted, restoring the OSX install from TimeMachine, everything I could think of, but all to no avail. Finally, thinking that maybe the OSX install I had safe on the secondary HD might still be okay (looking at it in gparted showed an EFI boot section everything), I opened up my MBP, swapped the drives around so that the HD is now the main drive, and the SSD the secondary, and renamed the drives so that the primary HD is now called 'Macintosh HD' and is first in the list of drives that appear when I manage to boot each 4th attempt. But, to my great disappointment, I still got exactly the same error. Can anyone offer any advice on how to: 1) Get my machine booting to a safe Snow Leopard install on the (now primary) HD? 2) Safely install Ubuntu on the (now secondary) SSD? Obviously the first is a top priority, as I need my machine in order to work! Then I can concentrate on moving my dev environment to Ubuntu, which I've been dying to do for ages. Thanks very much for any all assistance. Bed, now. I hate going to sleep defeated, but I've no idea what else to do. 'Night! Doug. PS -- apologies to any Geekuppers for the cross post. If you have a time machine backup I'd do the following. 1. Grab the OSX install CD and throw it into the drive 2. Using that CD flatten the OSX drive using the disk utility on the CD 3. Reinstall OSX 4. Attach time machine disk and restore from backup.

First, the advice around seems to be not to create any swap-space at all when using an ssd and to use the non-journalling ext2 format to increase limited ssd life. (feel free to disagree). In order to do this, you have to use the advanced install options (the bottom option) and these do ask you where you want to put grub. As part of the install, if you put grub on the ssd, it ought to run 'update-grub' and find both os's and let you have them OK. My view is you would do best to have grub on the same drive as the Ubuntu installation. Not sure about mac, but you have serious problems with Windows if you don't do that.

(feel free to disagree). I disagree. SSD write lifetime is longer than you think. http://www.storagesearch.com/ssdmyths-endurance.html We assume perfect wear leveling which means we need to fill the disk 2 million times to get to the write endurance limit. 2 million (write endurance) x 64G (capacity) divided by 80M bytes / sec gives the endurance limited life in seconds. That's a meaningless number - which needs to be divided by seconds in an hour, hours in a day etc etc to give... The end result is 51 years!
